Tessel Software, a fictional cloud software company, grows annual revenue from $1,000 million in fiscal year 1 (FY1) to $1,586 million in FY3. Sales rise 58.6%. Its year-end share price rises from $100 to $120, just 20%.
Assume a $200 holding at FY1's price. At FY3's price it is worth $200 × 1.20 = $240, with no deposits and before fees and taxes. Tessel pays no dividends in these years, so the price gain is the whole return.
The company grows much faster than your money. To judge a growth investment, you need to follow that expansion all the way to one share.
You are paying for what comes next
Growth investing focuses on businesses whose sales or earnings are expected to grow faster than their market or peers. A technology label or a high share price tells you little on its own.
The appeal is that a business can become much more profitable as it expands. Growth companies often reinvest instead of paying dividends, though some do both. A rich price needs strong future results to justify it.
Growth runway is the room a business has left to expand. A large potential market matters only if the company can win customers, serve them profitably and fund the work. A market-size estimate is no substitute for evidence of demand.
The value investigation asked whether future cash justified the price. Here, the harder part is judging how fast that cash can grow. The growth-quality checks help test whether expansion creates value.
Why a few winners matter so much
Stock returns are lopsided: a few enormous gains can pull up the overall result. That pattern is called positive return skew. A basket can do well even when many of its stocks disappoint.
In his 2018 study, Hendrik Bessembinder examined US stocks from 1926–2016. Roughly 4% of listed companies accounted for all the market's net dollar wealth creation above one-month Treasury bills. Gains and losses in the rest of the market offset one another relative to bills.
Four out of seven stocks lagged those bills over their lifetimes in the sample, even with dividends reinvested.
Those winners were found with hindsight across the whole market. The study does not show that buying stocks labeled growth will capture them. Diversification reduces dependence on guessing which company will be exceptional. Knowing that giants exist does not tell you which sapling to buy.
From company growth to one share
Tessel's revenue, shares and prices below are reported figures; dollars are US dollars and m means million. Sales per share uses actual year-end shares to illustrate ownership, not earnings. Changes are calculated before rounding.
| Measure | FY1 | FY3 | Change |
|---|---|---|---|
| Revenue ($m) | 1,000 | 1,586 | +58.6% |
| Year-end shares (m) | 102.5 | 112.5 | +9.8% |
| Sales/share ($) | 9.76 | 14.10 | +44.5% |
| Price ($) | 100 | 120 | +20% |
FY3 sales per share are $1,586 million ÷ 112.5 million = about $14.10. More shares spread the sales growth thinner: 58.6% for the company becomes 44.5% per share.
Set all three lines to 100 in FY1. A reading of 158.6 means a 58.6% increase; the gap is already opening in FY2.
The price-to-sales ratio, or P/S, supplies the remaining link between sales and the stock price:
In FY1, $1,000 million × 10.25 ÷ 102.5 million = $100. By FY3, P/S falls to about 8.51, down 17.0%. Investors pay less for each dollar of annual sales.
Tessel sells more, but you own a smaller fraction of it and the market values those sales at a lower multiple. Together, those changes leave the share price up 20%.
Write a growth thesis you can test
A useful thesis connects customers to cash and cash to one share.
- Find the source of growth. Tessel sells software subscriptions. The supplied figures do not split its revenue gains into new customers, extra purchases or price increases. Customer retention, competitors and the remaining runway need research.
- Follow the cash per share. FY3 GAAP net income is $45 million on $1,586 million of sales: less than $3 of profit per $100 of sales. That profit is after $250 million of stock-based compensation, payment in shares that costs owners. The cash case has to allow for both the cost of expansion and the extra shares.
- Test the price. At 8.51 times sales, compare expansion with improving profit margins, expansion with costs keeping pace, and slowing demand. If $120 works only when margins widen for years, the thesis depends on that improvement. A lower multiple than before does not settle whether the price is reasonable.
- Name what would change your mind. If the story depends on customers staying, a sustained fall in customer retention would challenge it. Look for that evidence before assuming a long runway.
A thesis that survives every possible result cannot guide a decision.
What the approach asks of you
Growth can slow at the same time investors cut the multiple they will pay. That gives the stock two ways to disappoint. Being right about an industry's future does not settle the return at your entry price.
The work continues with new reports, changing competition and evidence that may contradict your favorite story. The hard part is judging whether a setback delays the case or breaks it. Patience helps only while the business case holds up.
A diversified fund can reduce the work of choosing growth companies and the dependence on any one story. Market risk remains.
Tessel earns more research: investigate whether customers stay and whether expansion can produce growing cash per share, then test the price. Its runway remains unproven. Rising revenue has earned attention, not a purchase decision.
GARP and quality turns those concerns into three separate checks: growth, durability and price.
In short
- Growth investing pays for expectations about a business's future.
- Sales growth, growth per share and stock returns are different numbers.
- A few giant historical winners do not make future winners easy to identify.
- A useful growth thesis names the evidence that would break it.
